Aleksey Yeschenko commented on CASSANDRA-14080:
-----------------------------------------------
[~jjirsa] Nope. Talking about a JIRA specifically about writing out empty hint
buffers into empty files.
That would do it - although I'd prefer to just slap a second filter call
instead of combining the two here.
What I'd prefer even more is if we looked into why an empty hint file gets
written in the first place and taking care of it. Which would have the added
benefit of not having confusing empty files around.

> Jeff Jirsa added a comment - Yesterday
> Aleksandr Ivanov can you open a new JIRA and link it back to this one? It's
> possible that the original patch didn't consider 0 byte files (I don't have
> time to go back and look at the commit, and it was long enough ago that I've
> forgotten) - were all of your files 0 bytes?
> Not all, 8..10 hints files were with 0 size.
